If a giant oil company threatened to build a dangerous pipeline through your backyard, what would you do? For these activists, the answer was simple — take action to stop it.

Yesterday, ten activists peacefully blocked the entrance to a Kinder Morgan construction site in Coast Salish territory near Vancouver, Canada for several hours. Their bold action further delayed the construction of a tar sands oil pipeline that would violate Indigenous rights, threaten clean air and water for thousands of people, and contribute to global climate change.

One of those activists was Greenpeace founder Rex Weyler, who joined the action in solidarity with Indigenous communities to “preserve the ecological integrity of this coast for ourselves and future generations.”

Today’s blockade was just one in a series of inspiring acts of courage opposing Kinder Morgan’s destructive pipeline — and it certainly won’t be the last. Just over a week ago, more than 10,000 people joined a march and rally in solidarity with Indigenous communities to send a clear message of resistance to the oil industry.

The movement to put people over pipelines is gaining momentum — but we still need you.

Thousands gather in Metro Vancouver, British Columbia, for Indigenous-led “Protect the Inlet” mass mobilization against the Kinder Morgan Trans Mountain Expansion pipeline. The mobilization, led by Tsleil Waututh spiritual and cultural leaders, includes the building of a “watch house” grounded in the culture of the Coast Salish peoples, who, in the past would use watch houses to monitor their enemies and prepare to defend themselves in case of attack.

Taking down the oil industry, protecting land and water, and defending Indigenous rights is no small task; we’re going to need everyone to step up.
